ObjectiveTo investigate the color stability of infiltrant resin together with three other composites exposed to staining solution.MethodsThree types of anterior aesthetic composite resins (Filtek Z250, Filtek Z350 XT, and Beautiful Flow Plus F00) and artificial caries with Icon infiltrant resin were used. The samples were randomly divided into two groups (each contained 10 specimens): coffee solution and distilled water immersion for three weeks. Color parameters were determined with the Crystaleye spectrophotometer.ResultsArtificial caries lesions infiltrated by Icon showed much higher ΔE than those infiltrated by other aesthetic resins (Pstweek was significantly higher than those on the 2ndand 3rdweeks.ConclusionArtificial caries infiltrated with Icon was more vulnerable and susceptive to food color than those infiltrated with other aesthetic composite resins.
